ALL-STEEL CAR-DOOR.

Specification of Letters Patent.

Patented Dec. 24, rate.

Application filed July 12, 1915. Serial No. 39,284.

To all whom it may concern:

Be it known that I, ALBERT J. B. HARRIS, a citizen of the United States,residing at East Rochester, in the county of Monroe and State of N ewYork, have invented a certain new and useful Improvement in All-SteelCar-Doors, of which the following is a full,

clear, concise, and exact description, reference being had to theaccompanying drawings, forming a part of this specification.

This invention relates to improvements in all steel car doors.

An object of the invention is to provide an all steel door for box carsand the like which is provided with novel means for pre-,

vertical section, upon an enlarged scale taken on the line 22" of Fig.1, parts being broken away in order to prevent crowding of the drawing.Fig. 3 is a horizontal sectional view similar to Fig. 2 and taken on theline 3-31of Fig. 1. And Fig. 4 is a detail sectional view taken on theline H of 2.

In said drawing, 10 denotes the side walls of the car, the car beingprovided with a 2 bar side sill 11, floor boards 12, front and rear doorposts 13 and 14 and joist 15 forming the door lintel. Mounted on theupper face of the side sill 11 is a longitudinal wood sill 16 to whichthe floor boards are adapted to be nailed, said sill 16 being faced onits outer side With a longitudinally extending board 17 The side plateor joist 15 is faced on its outer side by fascia boards 18 and 19.

The door A, as shown, comprises a rectangular metal sheet 20 conformingto the size of the door opening, said metal sheet 20 being suitablybraced along its vertical outer edges by U shaped members 2121 and atits center by a similar member 22. Along the upper edge of the door A issecured a longitudinally extending S shaped member 23, (see Fig. 2),.the upper portion of which slides within a longitudinally extendingrecess formed by a plate 24 secured by bolts or otherwise to the upperstructure of the door frame. At its lower edge, the door is providedwith a stiflener in the form of an angle iron 25, the depending flange26 of which, on the side nearest the door frame has its lower edge 27curled upwardly to form an interlocking seal joint with a plate 127secured along the lower edge of the door frame, said plate 127 havingits outer edge bent downwardly as indicated at 28. To support the door,track supporting brackets 29 are secured to the side sill 11 and board17, said brackets 29 being suitably spaced as clearly indicated in Fig.1 and having attached to their outer ends a longitudinally extendingchannel 30 the flanges of which are inwardly turned as clearly indicatedin Fig. 2. The upper flange 31 of the channel forms a track on whichrides the rollers 32 mounted in roller brackets 33 secured to the angle25 along. the bottom of the door. Each of the roller carrying brackets33 has the inner leg thereof provided With a hobk shaped lip or flange34 at the bottom which is adapted to engage under the flange 31 of thechannel 30, thereby interlocking with the latter and preventingaccidental reinoval 3r outward swing of the door. To the outer face ofthe forward door post 13 is secured a 2 bar 35 having its outer flange36 spaced rom the outer face of the post and thereb adapted to receivethe forward edge of the door when the latter is in closed position andin this connection, it will be observed that said edge of the door issuitably strengthened by means of a plate 37 secured thereto as shown inFig. 3. Tohelp secure the 2 bar 35 and to suitably brace it, a pluralityof brackets 38 are provided of the form shown in Fig. 3 and riveted orotherwise secured as illustrated in said figure and in Fig. 1;

By referring to Fig. 3, it will be seen that the outer face of the rearpost 14 is extended beyond the face of the side boards of the car andhas secured thereto a vertically extending plate 39 the rear edge ofwhich is spacedfrom the side of the car and forms a recess or groovewithin which door.

From the preceding description, it will be seen that the front and rearedges of the door when closed are seated in grooves provided thereforand that the lower edge of the door is sealed by means of theinterlocking flanges 27-28, thereby securing a seal adapted to preventleakage of grain or similar bulk material. In addition to the foregoing,the interlocking seal' forming flanges 27 and 28 will serve to preventaccidental displacement of the door and thus cooperatewith theinterlocking lips 34 and track flange 31 in effecting this result.Similarly, at the top of the door, the interlocking 8 shaped member 23and overhanglng top guide 2 L prevent the door from swinging or fallingoutwardly. In addition to the foregoing, it will be observed that in theevent of accidental failure of the track or rollers for supporting thedoor at its lower edge the interlocking S shaped member 23 and top guide24 will serve as an auxiliary track and support for the door.

As will be understood by those skilled in the art, the various sectionsemployed for the track, seal forming flanges, top guide and otherelements, may be made either in the form of commercially rolledsections, pressed sections, or cast sections. Also,al though I haveherein shown and described what I now consider the preferred embodimentof my improvement, I am aware that changes and modifications may be madein the details of construction and arrangement of the parts withoutdeparting from the spirit of the invention and all such changes andmodifications are contemplated as come within the scope of the claimsappended hereto.

I claim: 1. In a car having a door opening and a slidable door forclosing said opening, a

combined track and fender extending horizontally along one edge of thedoor opening and having an inwardly extending upper flange, bracketssecured to the corresponding adjacent edgeof the door, said bracketscarrying rollers cooperating with said track,. said brackets beingprovided with outwardly extending flanges at their lower ends disposedbeneath said upper flange of the combined track and fender, said flangesthereby preventing upward and outward displacement of the door.

2. In a car having a door opening, the

combination with a plurality of brackets nasema secured to the car belowthe door opening and a channel shaped track secured to the outer ends ofsaid brackets, of a slidable door mounted on rollers secured tothebottom edge thereof, the car being provided with a plate alongthe loweredgeof the door opening, said plate having a downturned flange, and saiddoor being provided door mounted on rollers secured to the bottom edgethereof, the car being provided with a plate along the lower edge of thedoor opening, said plate having a downturned flange, and said door beingprovided with an upwardly turned hook shaped flange along its lower edgecooperating with said downturned flange'to form a seal, and hook shapedlips carried by said door along its lower edge'arrangedto engage beneaththe upper flange of said hannel track.

4. In a car having a side door opening, the combination with' a trackextending along the lower edge of the door opening, said trackconsisting of a hannel, of a slidable door, roller carrying bracketssecured to the lower edge of said door, said brackets having hook shapedlips arranged to engage beneath the upper flange of said channel track,rollers carried bylsaid brackets and riding upon the upper flange ofsaid channel track, a top guide plate secured to the side of the caralong the top edge of the door openidg, and a member S-shaped in crosssection secured to the top edgeof the door and cooperating with saidguide to prevent the door from swinging outwardly and serv-
